BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a golf ball retrieval and marking device.

2. Description of the Related Art

Golfing is a very popular sport that is enjoyed by people of many different ages. When playing a round of golf, the golf ball can be retrieved in many different situations, such as when putting. The golf ball is often retrieved, and its location is marked, when other golfers are putting. The golf ball is then positioned near the mark when it is the golfers turn to putt, and the mark is retrieved.

However, it can be difficult for a golfer to bend over and position and retrieve a golf ball and mark, especially when playing many holes. For example, it is often difficult for an elderly or injured golfer to bend at the waist and knees, and it generally becomes more difficult the longer the golfer plays. A golf ball retriever can be used to retrieve a golf ball without the golfer having to bend over and pick it up. Examples of golf ball retrievers are disclosed in U.S. Pat. Nos. 4,811,980, 5,328,174, 5,509,658 and 5,800,280. However, these golf ball retrievers do not alleviate the need to position and retrieve the mark.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 a is a perspective view of a golf accessory 100, in accordance with the invention, for retrieving a golf ball and marking its location, and FIG. 1 b is a bottom view of golf accessory 100. Golf accessory 100 is useful for retrieving a golf ball and marking its location without requiring the golfer to bend down. The golf ball is generally retrieved so it does not interfere with the play of other golfers. The position of the golf ball is marked so that it can be repositioned accurately when it is the golfer's turn to play.

The golf accessory can retrieve the golf ball because it includes a lower opening for receiving the golf ball, and grasping arms for holding the ball therein. The golf accessory can mark the location of the golf ball because it includes an arm which carries a magnet, wherein the magnet allows a mark to fall to the ground when the golf ball is received by the lower opening. In operation, the golf ball moves the arm away from the lower opening when the ball moves therethrough, and the magnet is moved away from the mark. In response, the mark falls to the ground and marks the location of the golf ball. In this embodiment, the ball can be retrieved and its location marked in a single motion, wherein the single motion consists of moving the golf ball through the lower opening.

The golf ball can be repositioned near the mark by pushing the arm so it is moved towards the lower opening and the ball is pushed out. When the arm is pushed out the lower opening, the mark can be coupled to the magnet. In this way, the mark can be retrieved. In this embodiment, the ball can be pushed out of the lower opening, and the magnet can be positioned so the mark can be coupled to it, in a single motion, wherein the single motion consists of moving the golf ball through the lower opening by pushing the arm. It should be noted that, in some embodiments, golf accessory 100 can be used as a golf ball retrieval device or a golf ball marking device. However, in this embodiment, it operates as both for illustrative purposes.

In this embodiment, golf accessory 100 includes a golf accessory body 101. In some embodiments, golf accessory 100 is used as a golf club so that golf accessory body 101 is shaped to operate as a golf head and is coupled to a golf club handle 103. In these embodiments, golf accessory body includes a striking surface 102 for striking the golf ball. Golf accessory body 101 includes a lower opening 105 (FIG. 1 b) which is sized and shaped to receive the golf ball, and an upper opening 104 (FIG. 1 a) for pushing the golf ball out of lower opening 105. In this embodiment, upper and lower openings 104 and 105 extend through golf accessory body 101. The golf ball can be pushed out of lower opening 105 in many different ways, such as by inserting a finger through upper opening 104.

FIGS. 1 c and 1 d are cut-away perspective views of golf accessory 100 showing an arm assembly 110. In this embodiment, arm assembly 110 includes an arm 109 carried by guide rails 107 and 108. Arm 109 is carried by guide rails 107 and 108 so it is repeatably moveable between positions towards and away from lower opening 105. Guide rails 107 and 108 are attached to golf accessory body 101, and arm 109 is slidingly engaged to them so that guide rails 107 and 108 guide the movement of arm 109 towards and away from lower opening 105.

In this embodiment, arm assembly 110 includes opposed grasping arms 111 a and 111 b positioned on opposed sides of lower opening 105. Grasping arms 111 a and 111 b grasp the golf ball when it is received by opening 105 by frictionally engaging it. In this way, the golf ball is retrieved by golf accessory 100. It should be noted that any of the arm assemblies discussed herein can include grasping arms, such as grasping arms 111 a and 111 b.

In this embodiment, golf accessory 100 includes a magnet 112 (FIGS. 1 b and 1 c) which is carried by arm 109 so it is proximate to an opening 106 of golf accessory body 101. Magnet 112 is carried by arm 109 so it moves towards and away from opening 106 in response to arm 109 moving towards and away from, respectively, lower opening 105.

Golf accessory 100 includes a mark which is repeatably moveable between positions coupled to and decoupled from magnet 112 in response to movement of arm 109. The mark can be coupled to magnet 112 when arm 109 is moved towards openings 105 and 106. Further, the mark is decoupled from magnet 112 in response to arm 109 being moved away from openings 105 and 106. The mark includes a magnetic material so that it is magnetically coupled to and decoupled from magnet 112. In accordance with the invention, arm 109 is moved away from openings 105 and 106 in response to engaging a golf ball, as will be discussed in more detail presently.

FIGS. 1 e and 1 f are side views of golf accessory 100, showing a mark 115 coupled to and decoupled from, respectively, magnet 112. In operation, golf accessory 100 is positioned proximate to golf ball 113, by using golf club handle 103, so that lower opening 105 is aligned with it.

For example, the arm assembly can be moved from the disengaged position to the engaged position by extending a golf ball through lower opening 105. Further, the arm assembly can be moved from engaged position to the disengaged position by extending a finger through upper opening 104.

The arm assembly can be included with golf accessory 140 in many different ways, such as by carrying it with golf accessory base 142. In some embodiments, the arm assembly, or a portion thereof, is mounted to golf accessory base 142 so they are a single integral unit. In other embodiments, the arm assembly, or a portion thereof, is mounted to golf accessory base 142 so they are separate units that can be separated from each other.

The arm assembly can be of many different types, such as those discussed in FIGS. 1 c and 2 a. However, several other embodiments of arm assemblies will be discussed in more detail below.

It should be noted that any of the arm assemblies discussed below can include grasping arms, such as grasping arms 111 a and 111 b (FIG. 1 g), although the grasping arms may not be shown for simplicity. Further, the grasping arms are typically carried by golf accessory base 142. It should also be noted that, in the embodiments discussed below, a mark can be coupled to and decoupled from a magnet, as discussed in more detail with FIGS. 1 e and 1 f.

FIGS. 5 a and 5 b are perspective views of an arm assembly 150 carried by golf accessory base 142. In this embodiment, arm assembly 150 includes an arm 145 pivotably coupled to golf accessory base 142. Arm 145 can be pivotably coupled to golf accessory base 142 in many different ways. In this embodiment, arm 145 is pivotably coupled to golf accessory base 142 with an arm bracket 146 and pin 147, wherein arm bracket 146 is attached to golf accessory base 142 and pin 147 extends through arm bracket 146 and arm 145. In this way, arm 145 is rotatable relative to arm bracket 146 and golf accessory base 142.

Arm 145 is repeatably rotatable between engaged and disengaged positions, as shown in FIGS. 5 a and 5 b, respectively. Arm 145 is moveable from the disengaged position to the engaged position by extending a golf ball, such as golf ball 113, through lower opening 105 so that it engages an engagement surface 145 a (FIG. 5 a) of arm 145. Arm 145 rotates away from golf accessory base 142 in response to the golf ball engaging engagement surface 145 a. Further, arm 145 rotates about pin 147 in response to the golf ball engaging engagement surface 145 a.

Arm 145 is moveable from the engaged position to the disengaged position by applying a force to an engagement surface 145 b, wherein engagement surface 145 b is opposed to engagement surface 145 a. The force can be applied to engagement surface 145 b in many different ways, such as by extending a finger through upper opening 104 (FIGS. 4 b, 4 c and 4 d) so that it engages engagement surface 145 b of arm 145. Arm 145 rotates towards golf accessory base 142 in response to the force applied to engagement surface 145 b, and the golf ball is moved out of lower opening 105. Further, arm 145 rotates about pin 147 in response to the force applied to engagement surface 145 b.

In this embodiment, arm assembly 150 includes magnet 112 which is carried by arm 145 proximate to its distal end. Magnet 112 is repeatably moveable between positions away from and towards opening 106, as shown in FIGS. 5 a and 5 b, respectively, in response to the rotation of arm 145 about pin 147. Magnet 112 is positioned towards opening 106 when arm 145 is in the disengaged position (FIG. 5 b) and magnet 112 is positioned away from opening 106 when arm 145 is in the engaged position (FIG. 5 a). Further, engagement surface 145 a is positioned towards lower opening 105 when arm 145 is in the disengaged position (FIG. 5 b) and engagement surface 145 a is positioned away from lower opening 105 when arm 145 is in the engaged position (FIG. 5 a). When arm 145 is in the disengaged position and magnet 112 is towards opening 106, mark 115 can be coupled thereto. Further, when arm 145 is in the engaged position and magnet 112 is away from opening 106, mark 115 is decoupled from magnet 112. In this way, mark 115 is repeatably moveable between coupled and uncoupled positions with magnet 112.

In this embodiment, golf accessory base 142 includes a closure magnet 144 positioned proximate to opening 106. Closure magnet 144 is positioned proximate to opening 106 so that it can couple to magnet 112 when magnet 112 is positioned towards opening 106. Closure magnet 144 is positioned proximate to opening 106 so that it can couple to magnet 112 when arm 145 is in the disengaged position. Closure magnet 144 is positioned proximate to opening 106 so that arm 145 is rotated towards golf accessory base 142 in response to the magnetic attraction between magnet 112 and closure magnet 144. Closure magnet 144 holds arm 145 to golf accessory base 142 when arm 145 is in the disengaged position.

Holding arm 145 to golf accessory base 142 is useful so that arm 145 does not undesirable move between the engaged and disengaged positions. The magnetic coupling between magnets 112 and 144 is chosen so that they are coupled together with a desired magnetic force. The magnetic force needs to be overcome when moving arm 145 from the disengaged position to the engaged position. Hence, a predetermined force needs to be applied to engagement surface 145 a to move arm 145 from the disengaged position to the engaged position. The predetermined force is typically applied to engagement surface 145 a by the golf ball. When a force less than the predetermined force is applied to engagement surface 145 a, arm 145 remains in the disengaged position. When a force less than the predetermined force is applied to engagement surface 145 a, the golf ball is not retained by golf accessory 140.

It should be noted that the predetermined force can be chosen in many different ways, such as by choosing the relative magnetic strengths between magnets 112 and 144. The predetermined force can also be chosen by choosing the number of closure magnets 144 included with golf accessory base 142. In general, as the number of closure magnets 144 included with golf accessory base 142 increases, the predetermined force increases. Further, as the number of closure magnets 144 included with golf accessory base 142 decreases, the predetermined force decreases.
